Pro's are nice, if your looking for loud and clear, im not a fan of the sound really, not too harsh of a tweeter for being aluminum, midbass is not that great IMO
we used to be Boston dealer, i had 2 sets of Pros, i thought they were good until we started messing with Hertz and then we dropped Boston and picked up Hertz and Audison, You can find Hertz HSK's for around 300-350, unless you want to jump up the MLK's for a good bit more
